NCDOT Closes I-87 Overnight Near Knightdale for Complete 540 Construction

The stretch of I-87 between Smithfield Road and Hodge Road near Knightdale shuts down at 11 p.m. tonight, with the closure running through 6 a.m. April 7. NCDOT announced the overnight window on April 2, flagging it as a turning point: contractors have moved past early land-clearing and grading and are now into bridge and roadway operations that can only be done safely with the lanes cleared.

Drivers who normally use that corridor overnight should plan for I-540 or U.S. 64 as alternate routes. NCDOT says the closure will be signed, and enforcement of reduced work-zone speeds is in effect.

The disruption is one piece of a much larger build. Phase 2 of the Complete 540 project covers 10.8 miles from I-40 near Garner to the existing I-540/I-87 interchange, and the scope reflects just how much infrastructure crews are assembling: six interchanges, 24 bridges, and multiple culverts across Wake County's southern and eastern corridor. The N.C. Turnpike Authority and NCDOT are jointly overseeing the work, with completion targeted for 2028. Nightly closures are expected to continue and potentially expand as structural work intensifies.

The project has been called the missing link of the outer 540 loop, and the communities waiting on it stretch across the region: Apex, Cary, Garner, Knightdale, Clayton, Fuquay-Varina, Holly Springs, and Raleigh all stand to see redistributed traffic once the toll segment opens. State planners have also cited freight movement and emergency evacuation capacity as strategic reasons for closing the loop, not just commuter relief.

The shift to bridge and ramp work also signals something local developers have been tracking: new interchanges tend to accelerate commercial and residential proposals on adjacent parcels, a dynamic that planners in Knightdale and Garner have already begun factoring into zoning discussions. The road is still years from opening, but its footprint is taking shape now, one overnight closure at a time.
